The first truly workable vacuum cleaner was invented at the very beginning of the 20th century, in 1901. It was a huge device that was used to clean the hotel. Today, a vacuum cleaner is a miniature device that is absolutely indispensable in any household, whether it is an ordinary apartment or a giant stadium. People all over the world are so accustomed to this, in general, uncomplicated device that life without it seems completely unbearable to many.
The vacuum cleaner quietly does a great job of removing dust in apartments and houses, and does it efficiently and quickly, increasing its owners a lot of free time that they would have spent cleaning the territory of the apartment using classic methods - with a bucket and a rag. The vacuum cleaner has made life easier for millions of men who do not have to go outside every week and shake carpets with improvised means, suffocating in clouds of dust.Oddly enough, the first vacuum cleaner that appeared in the world was a "wet" type.
Types of vacuum cleaners
Vacuum cleaners, according to the principle of their action, are for dry and wet cleaning. There are more complex devices that can combine both of these modes in their work. Vacuum cleaners that do dry cleaning (these are the most common because they are cheaper) may have a trash bag or may be equipped with a special dust container. Both the garbage collector can be freed from its load and reused. Vacuum cleaners operating in dry mode are based on the suction of air, which is cleaned by passing through filters and returned to the room.
What to look for when choosing a washing vacuum cleaner
When a customer comes to the store to buy a vacuum cleaner, he is shocked by the number of models lying and standing on the shelves, as well as the number of manufacturers. Therefore, in order not to get into trouble, he needs to have an idea about the capabilities and functions of the product that he wants to use at home. If we are talking about a vacuum cleaner for wet cleaning, then you need to focus on the following device parameters:
- power of the proposed device;
- filtration principle;
- availability of additional accessories;
- dimensions and weight of the product;
- dimensions of the water tank;
- noise during operation.
The high power of the vacuum cleaner is, as they say, a double-edged sword. A vacuum cleaner with insufficient power, of course, will not be effective enough, and a device that is too “strong” can simply ruin carpets by pulling threads out of them.The filtration system installed in the vacuum cleaner is very important. Vacuum cleaners with filters in the form of ordinary bags are the least effective. They can be paper - disposable, and cloth.
As a rule, inexpensive devices are equipped with bags, and they, unfortunately, are a breeding ground for mites and bacteria. Important: paper bags are more hygienic because they are simply thrown away after filling. Containers as dust collectors are more efficient. They do not need to be changed, they are simply washed. These filters trap debris and dust much better. True, vacuum cleaners equipped with these container filters are noisier.
